 * <p>This ServantActivator stub is an optional base for the

 * servant activators. This stub cannot accept remote invocations, as

 * methods in {@link ServantActivatorOperations} take POA as one of parameters.

 * Both JDK 1.5 API and OMG specifies that POA is a local object that must not

 * be transferred to the remote invocation target.

 * </p><p>

 * You do not need to derive your servant activator from this stub,

 * it is enough to implement the {@link ServantActivator} interface.

 * But you may choose to do this if you need the functional

 * {@link #_ids()} method or want to keep default behavior during

 * the incarnation or etherialization.
